The HP TouchPad, which will be the first webOS tablet, is touted to be the only tablet which can compete with the iPad and Honeycomb tablets. The RIM Blackberry Playbook hasn’t seen very good sales yet. webOS on the tablet has received some great reviews though, just like its smartphone counterpart.

Thanks to HP’s massive distribution network and reach, the HP TouchPad is expected have much better sales than the Playbook. We have seen glimpses of the TouchPad before, but the pricing details haven’t been announced yet. Today, a screenshot of Walmart’s inventory system was leaked by PreCentral, which reveals that the TouchPad will be priced at $599 for the 32 GB Wi-Fi version. The iPad 2 32 GB Wi-Fi is also priced the same, so I’m guessing HP doesn’t plan to compete on price.

Walmart will also be selling the Touchstone charger dock for $79.98, and a webOS Bluetooth keyboard for $69.98. The HP TouchPad may be launched by the first week of June.

The HP TouchPad comes with a 9.7 inch display with a resolution of 768 x 1024 pixels. It will run webOS 3.0 and comes with a dual core Qualcomm Snapdragon 1.2 GHz processor. It has 32 GB internal storage and comes with Bluetooth and Wi-Fi 802.11 b/g/n. It is powered by a 6300 mAh battery.
